Holley Muscle Series Centerbolt Valve Covers

Holley Muscle Series centerbolt valve covers present a no-frills, modern style with prominent raised GM "Chevrolet and Bowtie" logos. Intended as an alternative to the existing GM ZZ6 accessories, a Holley GM Muscle Series cover is the perfect addition to your engine bay if you're searching for a subtle custom variation from the OEM options. They feature a generous internal height for exceptional valve train clearance, and include pre-installed internal baffling, polished mounting hardware, and oil fill/PCV grommets.

Holley Muscle Series centerbolt valve covers feature:

* Clean, modern styling with high-definition "Chevrolet and Bowtie" logo
* Specifically designed for GM ZZ6 engines, but will fit all small block Chevy applications with center bolt-style cylinder heads
* Diecast aluminum construction ensures high detail and reduces the opportunity for warping of the valve cover flange and oil leaks
* Emissions-compliant valve covers include pre-installed internal oil baffles, as well as an oil fill plug and PCV grommet
* Multiple finishes are available
